Instructional Vids

I've been approached by a fairly large company (holding off on the name at this point, but you've heard of them) to make some instructional videos. This is a pretty exciting opportunity, but I'd like to find out what kind of techniques and skills people would actually watch, or want to learn.

So, what are some things that you'd say "I'd really like to learn how to do that?" or things that you think would be of value to someone looking to start on bass that they'd benefit from?
